As his sexual awareness increases, Gwang-ho no longer likes the scent of his
mother, who wears heavy make-up as she sells cosmetics door-to-door. Eun-sook,
an assistant nurse who is the complete opposite of Gwang-ho's mother, becomes
the object of all of Gwang-ho's attention and affection. Absorbed in his
thoughts, Gwang-ho is oblivious of the news of the president's death and the
picture of the new president replacing the late president in his classroom.
Gwang-ho receives a letter of luck and starts sending it to people around him.
As those people start vanishing, Gwang-ho is racked with guilt, suspecting the
letter of luck is the cause of their disappearance.
